Description

Technical Field

[0001] This invention relates to the field of marine engineering equipment technology, and in particular to a multi-stage buffer mast base structure. Background Technology

[0002] In the field of marine engineering, mast bases are an important component of marine engineering equipment, mainly used to support and stabilize various offshore structures, such as offshore communication masts, offshore cranes, and offshore wind power towers. These bases need to possess high stability and corrosion resistance to adapt to the complexity and harshness of the marine environment.

[0003] However, existing technologies still have the following problems: First, although the mast base has a multi-stage buffering function, in order to ensure stability, the mast base is large in size and heavy in weight, which makes it difficult to move during short-distance transportation and position adjustment. It requires the use of power tools such as trolleys for adjustment, which has certain limitations. Furthermore, the buffering structure used in the multi-stage buffering of the mast base, such as the hydraulic damper, can only achieve the buffering effect when subjected to damping force. The buffering direction is unidirectional and cannot effectively dampen the tilt direction of the mast. Therefore, we propose a multi-stage buffering mast base structure. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a new technical solution for a multi-stage buffer mast base structure.

[0005] The objective of this invention is achieved as follows: a multi-stage buffer mast base structure, including a base body, further comprising:

[0006] An auxiliary moving mechanism is provided, which consists of a rotating component and multiple sets of spoked wheels. The auxiliary moving mechanism is located inside the base body. A mounting groove is provided at the center of the upper surface of the base body. The multiple sets of spoked wheels are all rotated by the rotating component to approach the mounting groove.

[0007] The buffer mechanism consists of multiple sets of anti-misalignment plates and multiple sets of driving components. The anti-misalignment plates are connected to the driving components in a transmission manner, and the anti-misalignment plates are set close to the center of the mounting slot through the driving components.

[0008] Optionally, the rotating component includes a servo motor and multiple sets of rotating shafts, which are mutually driven. One end of the output shaft of the servo motor is keyed to one of the sets of rotating shafts. The spoke wheel is rotatably arranged with the rotating shafts, and a steering component is provided between the two sets of rotating shafts and the spoke wheel that are aligned with each other.

[0009] Optionally, transmission rods are fixedly installed at both ends of the rotating shaft, and a first bevel gear transmission structure is provided between the close ends of two adjacent sets of transmission rods. A transmission hole is opened on the outer side of the base body, and the transmission rods and the rotating shaft are rotatably installed inside the transmission hole. The servo motor is fixedly installed inside the transmission hole.

[0010] Optionally, a storage hole is provided around the bottom of the base body, and the inside of the storage hole is the same as the inside of the mounting groove. The spoke wheel rotates into the storage hole via a rotating shaft.

[0011] Optionally, the steering component includes a rotating plate and a driven gear. The rotating plate is fixedly connected to the rotating shaft. A connecting seat is rotatably connected to the outer side of the spoke wheel. The rotating plate is rotatably connected to the connecting seat. The driven gear is rotatably mounted on the upper surface of the rotating plate. Two sets of receiving holes are provided with tooth grooves on their inner walls. The driven gear meshes with the tooth grooves.

[0012] Optionally, a protective shell is fixedly installed on the upper surface of the rotating plate, the driven gear is rotatably installed inside the protective shell, a second bevel gear transmission structure is rotatably installed inside the protective shell, the second bevel gear transmission structure is connected to the driven gear, a drive gear is rotatably installed on the bottom of the rotating plate through the second bevel gear transmission structure, and a rotating gear is fixedly installed in the middle of the upper surface of the two sets of connecting seats, the rotating gear meshes with the drive gear, and the rotating gear is rotatably installed on the bottom of the rotating plate.

[0013] Optionally, the buffer mechanism further includes multiple sets of buffer plates, the buffer plates being located between two adjacent sets of receiving holes, and a first spring hydraulic damper being provided between the buffer plates and the mounting groove, and the driving component being located between the buffer plates and the anti-misalignment plate.

[0014] Optionally, the driving component includes a second spring hydraulic damper, the movable end of which is rotatably connected to the anti-misalignment plate, and the second spring hydraulic damper is slidably connected to the base body.

[0015] Optionally, the second spring hydraulic damper is provided with a guide block at its bottom, and a guide rail is provided around the upper surface of the base body. The guide block is slidably installed on one side of the guide rail, and the guide rail is inclined.

[0016] Optionally, a squeezing plate is fixedly installed on the upper outer side of the buffer plate, and a rotating shaft is rotatably installed inside the mounting groove, with rocker plates fixedly installed at both ends of the rotating shaft. The rocker plates are located at the bottom of the squeezing plate and the second spring hydraulic damper.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the base body can be easily moved a short distance by means of an auxiliary moving mechanism, and the specific position can be adjusted according to the usage, thereby improving the overall convenience. In addition, the spoke wheel can also be rotated into the mounting slot for mast insertion. The auxiliary buffering mechanism buffers the force generated when the mast sways. Therefore, it not only improves the convenience of the mast base, but also improves the buffering effect of the mast base.

[0018] Secondly, the lever is moved away by the cooperation of the rocker, the pressure plate and the pivot. When the mast sways, the pressure plate is pressed, causing the pressure plate to tilt outward. Then, the pressure plate presses the rocker, which in turn presses the second spring damper. This causes the second spring damper to actively press the mast, turning passive into active, and quickly preventing the mast from swaying and tilting too much. Therefore, the stability of the mast is effectively improved.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1 to 11 As shown, the primary buffer mast base structure includes a base body 2, and also includes:

[0035] The auxiliary moving mechanism 1 consists of a rotating component 102 and multiple sets of spoked wheels 101. The auxiliary moving mechanism 1 is located inside the base body 2. A mounting groove is provided at the center of the upper surface of the base body 2. The multiple sets of spoked wheels 101 are all rotated by the rotating component 102 to approach the mounting groove.

[0036] like Figures 1 to 11As shown, due to the design of the spoked wheel 101, the spoked wheel 101 can facilitate the movement of the base body 2, and the spoked wheel 101 can rotate to approach the inside of the mounting groove to compress the mast inserted into the mounting groove. This makes the spoked wheel 101 not only convenient for the base body 2 to move, but also buffer the mast when it sways. The spoked wheel 101 has strong impact resistance. When it is severely damaged, the impact force will be distributed to each spoke, and it is not easy to deform. Thus, it can buffer the mast for a long time.

[0037] Secondly, because the mounting slots on the upper surface of the base body 2 on the market are designed to accommodate the mast, the diameter of the mounting slot holes is roughly the same as that of the mast to facilitate quick insertion of the mast. This results in the mast needing to overcome friction when inserted into the mounting slot. However, the design of the spoke wheel 101 can reduce the difficulty of inserting the mast into the mounting slot, thereby improving the practicality of the mast base.

[0038] The buffer mechanism 3 consists of multiple sets of anti-misalignment plates 303 and multiple sets of drive components 304. The anti-misalignment plates 303 are connected to the drive components 304 in a transmission manner, and the anti-misalignment plates 303 are set close to the center of the mounting slot through the drive components 304.

[0039] like Figures 1 to 11 As shown, because the anti-misalignment plate 303 is designed to be close to the center of the mounting slot through the drive component 304, the anti-misalignment plate 303 can actively squeeze close to the mast during the mast swaying process, thereby quickly straightening the mast and avoiding excessive mast swaying.

[0040] Furthermore, the rotating component 102 includes a servo motor 1025 and multiple sets of rotating shafts 1027. The multiple sets of rotating shafts 1027 are mutually driven. One end of the output shaft of the servo motor 1025 is keyed to one of the sets of rotating shafts 1027. The spoke wheel 101 is rotatably mounted on the rotating shafts 1027. A steering component 103 is provided between the two sets of rotating shafts 1027 and the spoke wheel 101 that are aligned with each other. A transmission rod 1023 is fixedly installed at both ends of the rotating shaft 1027. A first bevel gear transmission structure 1024 is provided between the close ends of two adjacent sets of transmission rods 1023. A transmission hole is opened on the outside of the base body 2. The transmission rods 1023 and the rotating shafts 1027 are rotatably mounted inside the transmission hole. The servo motor 1025 is fixedly mounted inside the transmission hole.

[0041] Specifically, such as Figures 1 to 11 As shown, multiple sets of extension shells 1021 communicating with the inside of the transmission hole are fixedly installed around the outer side of the base body 2. The transmission rod 1023 and the first bevel gear transmission structure 1024 are both located inside the extension shells 1021, thereby preventing the transmission rod 1023 and the first bevel gear transmission structure 1024 from being exposed and affecting their normal operation during transmission.

[0042] like Figures 1 to 11 As shown, through the design of the servo motor 1025, since the servo motor 1025 has a self-locking function on the output shaft, it can prevent the spoke wheel 101 from becoming loose, thus preventing the base body 2 from being moved easily. Furthermore, through the design of the first bevel gear transmission structure 1024, the transmission rod 1023, and the rotating shaft 1027, the servo motor 1025 can simultaneously drive multiple sets of spoke wheels 101 to rotate at the same time, quickly switching to the bottom of the moving base body 2 or the inner wall of the mounting groove.

[0043] It should be noted that the servo motor 1025 mentioned above can be used with a brake function. The servo motor 1025 with a brake is already a mature technology. Those skilled in the art should know how to install and use the servo motor 1025 to prevent the spoke wheel 101 from resetting and shaking after rotating to the designated position. Therefore, the present invention will not elaborate on this.

[0044] Furthermore, a storage hole 4 is provided around the bottom of the base body 2, and the interior of the storage hole 4 is the same as the interior of the mounting groove. The spoke wheel 101 rotates into the storage hole 4 through the rotating shaft 1027.

[0045] like Figures 1 to 11 As shown, the design of the storage hole 4 allows the spoke wheel 101 to be easily hidden when not in use, reducing the overall footprint and improving the convenience of the mast base.

[0046] Furthermore, the steering component 103 includes a rotating plate 1031 and a driven gear 1032. The rotating plate 1031 is fixedly connected to the rotating shaft 1027. A connecting seat 1026 is rotatably connected to the outer side of the spoke wheel 101. The rotating plate 1031 is rotatably connected to the connecting seat 1026. The driven gear 1032 is rotatably mounted on the upper surface of the rotating plate 1031, and two sets of receiving holes 4 are aligned and have toothed grooves 5 on their inner walls. The driven gear 1032 meshes with the toothed grooves 5. A protective shell 1033 is fixedly mounted on the upper surface of the rotating plate 1031. Wheel 1032 is rotatably mounted inside protective shell 1033. A second bevel gear transmission structure 1034 is rotatably mounted inside protective shell 1033. The second bevel gear transmission structure 1034 is connected to the driven gear 1032. A drive gear 1035 is rotatably mounted on the bottom of rotating plate 1031 through the second bevel gear transmission structure 1034. A rotating gear 1036 is fixedly mounted on the middle of the upper surface of two sets of connecting seats 1026. The rotating gear 1036 meshes with the drive gear 1035. The rotating gear 1036 is rotatably mounted on the bottom of rotating plate 1031.

[0047] like Figures 1 to 11As shown, through the design of the steering component 103, when the four sets of spoke wheels 101 rotate to the bottom of the base body 2, the two sets of spoke wheels 101 that are aligned can be steered by the engagement of the driven gear 1032 with the tooth groove 5, and through the second bevel gear transmission structure 1034, the drive gear 1035 and the rotating gear 1036, and are axially aligned with the remaining two sets of spoke wheels 101, thereby facilitating the movement of the base body 2. When the two sets of spoke wheels 101 that are aligned rotate upward, they will reset and rotate, so that all four sets of spoke wheels 101 are facing the center of the mounting groove, reducing the friction when the mast is inserted into the mounting groove.

[0048] Specifically, such as Figures 1 to 11 As shown, a connecting rod 1022 is fixedly installed between the rotating plate 1031 included in the steering component 103 and the rotating shaft 1027 of the teammate, and connecting rods 1022 are also fixedly installed between the connecting seats 1026 of the remaining two sets and the rotating shafts 1027 of the remaining two sets.

[0049] Furthermore, the buffer mechanism 3 also includes multiple sets of buffer plates 302, the buffer plates 302 are located between two adjacent sets of receiving holes 4, and a first spring hydraulic damper 301 is provided between the buffer plate 302 and the mounting groove, and the driving component 304 is provided between the buffer plate 302 and the anti-misalignment plate 303.

[0050] like Figures 1 to 11 As shown, due to the long overall length of the mast, the mast will tilt when it sways, which will squeeze the buffer plate 302 to tilt. The first spring hydraulic damper 301 can reduce the swaying force first.

[0051] Furthermore, the drive component 304 includes a second spring hydraulic damper 3041, the movable end of which is rotatably connected to the anti-misalignment plate 303, and the second spring hydraulic damper 3041 is slidably connected to the base body 2; a guide block is provided at the bottom of the second spring hydraulic damper 3041, and a guide slide rail 3043 is provided around the upper surface of the base body 2, the guide block is slidably installed on one side of the guide slide rail 3043, and the guide slide rail 3043 is inclined; an extrusion plate 3045 is fixedly installed on the upper outer side of the buffer plate 302, a rotating shaft 3042 is rotatably installed inside the mounting groove, and rocker plates 3044 are fixedly installed at both ends of the rotating shaft 3042, the rocker plates 3044 being located at the bottom of the extrusion plate 3045 and the second spring hydraulic damper 3041;

[0052] like Figures 1 to 11As shown, through the design of the drive component 304, when the buffer plate 302 is tilted by the mast, it will drive the compression plate 3045 to compress the rocker plate 3044, causing the upper end of the rocker plate 3044 to tilt up and compress the bottom of the second spring hydraulic damper 3041. This causes the second spring hydraulic damper 3041 to extend the guide rail 3043 and move in the tilting direction, indirectly realizing the active compression of the mast, thus turning passive into active, quickly supporting the mast, and effectively improving the buffering effect of the mast base.

[0053] The above description of the embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
